BATTERY SPECIFICATION 'Olmng part Of Letters Patent N0. 787,715, dated April 18, 1905.

Application led October 20, 1904:. Serial No. 229,216.

To all whom it may concern.:

Be it known that I, WILLIAM C. BANKS, a citizen of the United States of America, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Batteries, of which the following isa specification, reference being had to the accompanying drawings, forming part of the same, in Which- Figure l is a central vertical sectional view of a battery embodying my invention, showing the depolarizer on one side. Fig. 2 is a side elevation, partly in section, of the standard of said battery; and Fig 3 is a plan view of the basket-bottom or plate.

My invention relates to batteries, particularly primary batteries; and it consists,'essentially, in certain features of construction whereby the device is rendered susceptible to ready and easy cleaning and recharging, while at the same time it accomplishes a continuous, even, and long discharge of current.

J is the jar or cell, of glass or other suitable material, and, as represented, about six by eight inches, though dimensions are not of particular moment. A

`In the cell I locate a standard S, preferably in the form of a porcelain tube t, extending vertically upward to the top line of the jar, supported on feet F, usually three or more, spreading so as to neatly fit the jar and support the tube about centrally therein. I do not limit myself to a device in which the tube and feet are formed in one piece. At the kneesnIpr'eferably provide seats for the zinc Z, though this is not imperative, as it might be supported by the are of the standard just Where the feet or legs join the tube, or even elsewhere.

' I also prefer to provide lugs Z at the side of the tube to aid in supporting the basket-bottom. On its seat or seats (those at n, as here shown) I locate the zinc Z, and immediately above it I place the basket-bottom b, which may also be of porcelain, though tin would do if properly insulated from the Zinc, being preferably perforated to permit the excitingliquid to pass in and out and having a central orice to pass over the tube part of the standard S. The perforations; however, are so placed, as shown, as not to come immediately over the zinc, (which may also act as a support to the basket,) and a rubber ring 1 or other insulation is preferably interposed between the bottom b and the zinc Z. A second rubber ring r is preferably placed about the standard, immediately above'the line of plate I), to prevent oxid from sifting through. On said bottom I place a cylinder B, usually of perforated tin, for holding the depolarizer, black oxid of copper preferred. The bottom rests on the lugs Z, if there be any, and the insulation ard and up to the zinc, to which it may be riveted, as at c,'as has been my practice for some time. Then when the basket is filled with oxid D and the exciting liquid, which may be a soda solution, is introduced into the jar the battery is ready for use. A film of oil 0 may be spread'over the exciting solution, if desired. Now when the oxid or zinc is exhausted the entire solid contents of the jar may readily be removed by simply seizing the standard and vlifting out the entire mass. The clamp-terminal is readily removed from the basket, the cylinder and zinc stripped from the standard and thrown away, and the remaining parts are ready to receive a new charge. The bottom 'b and the cylindrical part B of the basket might be made in onepiece; but I Iprefer two for economy and ease of recharging and usually make the bottom of a heavier piece, with a groove g to assist in the ready and accurate placing, and'I then retain said plate for use in recharging. It will be found that my arrangement of the Zinc terminal Wire` within the tube prevents -it being eaten olf at the solution-line s, as is now very coml. In a battery, the combination of a jar, a

standard supporting the remaining parts and having a tube portion supported above the bottom, a zinc supported on said standard, a basket substantially concentric with the tube located above said zinc, and terminals, all substantially as set forth.

2. In a battery, the combination of a jar, a standard supporting the remaining parts and having a tube portion supported above the bottom, a zinc supported on said standard, a basket substantially concentric with the tube located above said zinc, and terminals, one of which leads down through the tube and to its appropriate element, all substantially as set forth.

3. In a battery, the combinationof a jar, a standard supporting the remaining parts and having' a tube portion supported above the bottom, a zinc supported on said standard, a basket substantially concentric with the tube composed of a cylinder and a base-plate, located above said zincand terminals, all substantially as set forth.

t. In a battery, the combination of a jar, a standard supporting the remaining parts and having a tube portion supported above the bottom, a zinc supported on said standard, a basket substantially concentric with the tube located above said zinc and at least partially supported by it, and terminals, all substantially as set forth.

5. In a battery, the combination of a jar, a standard supporting the remaining parts and having a tube/portion supported above the bottom and provided with seats for the Zinc and supporting-lugs for the depolarizer-basket, a Zinc supported on saidstandard, a baslocated above said zinc, and terminals and in sulators, all substantially as set forth.

7. In a battery, the combination of a jar, an insulated zinc, a depolariZer-basket placed above said Zinc, an insulator interposed between said zinc and said basket, and supports, terminals and connections, all substantially as set forth.

8. In a battery, the combination of a jar, a standard, a zinc supported on said standard above the bottom, a basket located above said Zinc and sustained by the standard, and ter minals, all substantially as set forth.

In testimony whereof I'have signed my name to this specification, in the presence of tvvo subscribing Witnesses, this 25th day of April,1904.

WM. C. BANKS.
